This is a decorative screw-in green LED C7 light bulb, suitable for use in candelabra sockets (E12). The diffuser is made of high-impact plastic, with a faceted pattern etched into the finish. This bulb will not provide significant usable light, but if decorative incandescent green candelabra-base light bulbs are now being used, this LED C7 bulb will drop the associated electricity use to just 1/10th of a watt.
